Camarray-Arducam 12MP Synchronized Stereo Camera Bundle Kit

Specs for Arducam 12MP Synchronized Stereo Camera Bundle Kit

Introduction

​This Arducam 12MP Synchronized Stereo Camera Bundle Kit is capable of running two 12MP IMX477 Camera Modules simultaneously through a single MIPI CSI-2 camera slot connection on popular embedded systems like Raspberry Pi, Jetson Nano, and Jetson Xavier NX. It consists of two 12MP High Quality IMX477 camera module and an Arducam stereo camera HAT. The stereo camera HAT is enabled by ArduChip to disguise the dual-camera connection as a single camera to be accepted by the single-board computers. You can use this bundle to build your stereo camera system for depth-related vision applications or upgrade your IMX219 stereo setup.

What is Camarray

Camarray is a series of embedded stereo cameras and multiple camera solutions from Arducam. Upgraded from Arducam Sync Stereo Camera HAT, the Camarry can disguise up to 4 synched camera modules as a single camera slot connection to embedded systems like the Raspberry Pi, Jetson nano, and Xavier NX. With Arducam camarray, your camera connectivities are no longer limited to the camera connectors on the motherboard or the carrier board. Along with Arducam-provided camera drivers, more flexibility is added to your multi-camera applications.

Quick Start Guide for Arducam 12MP Synchronized Stereo Camera Bundle Kit

Hardware Setup​​

B0265R 02 1
B0265R 01

Check the Driver​​

There are 3 drivers for Raspberry Pi:

  • Official driver
  • Arducam MIPI camera driver
  • Arducam V4L2 driver

The MIPI camera driver does not conflict with the official driver. The V4L2 driver conflicts with the official driver. Arducam 12MP Synchronized Stereo Camera uses the official driver or MIPI camera driver. If you want to use the official commands like raspistill and raspivid, you need to check if the V4L2 driver is installed first, if so, uninstall it.

1.Type the following command:

sudo nano /boot/config.txt

2.Press【PageDown】several times or scroll your mouse wheel down to check if there is “dtoverlay=arducam”.

dtoverlayarducam”

1)If you see “dtoverlay=arducam”, modify it as “#dtoverlay=arducam” to uninstall the V4L2 driver. Press 【Ctrl+X】, 【Y】,【Enter】to save the change and exit. Finally, type the following command to reboot.

sudo reboot

2)If you don’t see “dtoverlay=arducam”, it means you haven’t installed the V4L2 driver. Please follow the below steps to continue.

3)If you don’t see “#dtoverlay=arducam”, it means that Arducam’s V4L2 driver has been installed before, but it is uninstalled. Please follow the below steps to continue.

Check the Camera

1.Go to the main menu and open the Raspberry Pi Configuration tool.

check camera1

2.Select the Interfaces tab and ensure that the camera is enabled:

check camera2

3.Reboot your Pi

4.Check whether the camera is detected

vcgencmd get_camera
whether the camera is detected
  • detected=1 means the camera is detected. (The camera is OV5647, IMX219, or IMX477.)
  • detected=0 means the camera is not detected. You might have to check the ribbon connection correctly, then reboot the Raspberry Pi.

First Use with Official Driver

You can refer to the page for instructions. Or refer to this page for the official commands.

1.Preview the camera feed in real time

Execute the official native command raspistill

raspistill -t 0

Press 【Ctrl】+【C】 to exit the preview.

raspistill和raspivid1

Execute the official native command raspivid

raspivid -t 0
raspistill和raspivid2

It can be zoomed into the display.

raspistill -t 0 -p 800,100,1024,768
raspivid -t 0 -p 800,100,1024,768

800,100 indicates the starting position of the window (top left corner).
1024,768 indicates the size of the image after scaling.

2.Save an image

Take a picture after a two-second (time in milliseconds) delay and save it as image.jpg.

raspistill -t 2000 -o image.jpg
pi doc
imx477 pic dual

Take a custom sized photo

raspistill -t 2000 -o image.jpg -w 1920 -h 1080
Take a custom sized photo imx477 dual

3.Save a video

Record 10 seconds (time in milliseconds) of h264 video and save it as image.h264.

raspivid -t 10000 -o video.h264 
save a video imx477 dual command
pi doc imx477 dual

Double click “video.h264” file, it will call the VLC media player to play.

First Use with MIPI Camera Driver

1.Download and Install the SDK

Download the SDK library:

git clone https://github.com/ArduCAM/MIPI_Camera.git
download sdk1
Downloading
download sdk2
Download completed (it usually takes a few minutes)

Enter the SDK directory:

cd MIPI_Camera/RPI/
Enter the SDK directory

Install SDK

make install
install sdk

Enable I2C_0

chmod +x enable_i2c_vc.sh
./enable_i2c_vc.sh
enable i2c

Press 【y】, 【Enter】 to reboot Pi.

2.Compile demo

Enter the directory:

cd MIPI_Camera/RPI/

Compile demo:

make clean && make
complie demo

1.It doesn’t matter if opencv reports an error

2.The demo program needs to be recompiled after modification.

3.Run demo (through the “arducamstill” command)

This is a comprehensive application, user can use it to preview, get image in different format and fine tuning the image quality.

3.1Get Help

Execute the following command to get a description of the parameters of the arducamstill command.

Be sure to run it in the MIPI_Camera/RPI directory.

get help imx477 dual

3.2Preview the camera feed in real time

Check the supported modes.

./list_format

You can only run the modes listed in the results. For example, you can only run mode1 or mode2 here.

mode1 mode2 imx477 dual

Run mode0:

./arducamstill -t 0 -m 0
run mode0
run mode 0 pic dual

Run mode1:

./arducamstill -t 0 -m 1
run mode1
run mode1 pic dual

The default display is windowed and scaled. If you need to change the window size, you have to do it in the demo program.

Difference between mode0 and mode1

1.The resolution of mode0 is 4056×3040, the resolution of mode0 is 8112×3040.
2.The frame rate of mode0 is higher than that of mode1.
3.Stretch the image of mode0 horizontally by a factor of twice and it will look exactly like the image of mode1!

3.3Save an image

#mode0

Take a picture after a two-second (time in milliseconds) delay and save it as image.jpg.

./arducamstill -t 5000 -m 0 -o image.jpg
save an image imx477 dual

NOTE

This demo’s exposure and gain functions are controlled via the keyboard arrow keys, so the demo will always wait for keyboard commands.

Press 【Ctrl】+【C】 to exit preview.

The image is saved in the directory /home/pi/MIPI_Camera/PRI.

save image1
save image2

#mode1

Take a picture after a two-second (time in milliseconds) delay and save it as image.jpg.

./arducamstill -t 5000 -m 1 -o image.jpg
save image mode2
